Reducing computed tomography radiation dose in diagnosing pulmonary embolism
BACKGROUND AND OBJECTIVE Computed tomography angiography plays a major role in the diagnosis of pulmonary embolism. Radiation dose associated with it is a major concern; therefore it is important to optimize protocols and techniques to ensure minimum radiation dose. METHODS The study compares two protocols i. Conventional Timing Bolus CT protocol and Delayed Timing Bolus protocol used to assi...
متن کاملIncidental Findings in Patients Evaluated for Pulmonary Embolism Using Computed Tomography Angiography
Introduction: Pulmonary embolism (PE) is a common lethal disease that its clinical symptoms may be seen in many other diseases. Computed tomography pulmonary angiography (CTPA) is a valuable diagnostic modality for detection of PE. In addition, it can accurately detect the other diseases with clinical symptoms similar to PE. The aim of this study is to evaluate the frequency of PE and nonemboli...
متن کاملSpiral computed tomography for pulmonary embolism.
Spiral computed tomography pulmonary angiography is increasingly used in the non-invasive investigation of patients with suspected pulmonary embolism. This review will focus on current techniques and indications with an explanation of the computed tomography signs of pulmonary embolism, possible pitfalls in interpretation and limitations of the technique.
متن کاملSpiral computed tomography for acute pulmonary embolism.
There is still considerable debate about the optimal diagnostic imaging modality for acute pulmonary embolism. If imaging is deemed necessary from an initial clinical evaluation such as d-dimer testing, options include nuclear medicine scanning, catheter pulmonary angiography, and spiral CT. In many institutions, spiral CT is becoming established as the first-line imaging test in daily clinical...
متن کاملMultidetector computed tomography for acute pulmonary embolism.
BACKGROUND The accuracy of multidetector computed tomographic angiography (CTA) for the diagnosis of acute pulmonary embolism has not been determined conclusively. METHODS The Prospective Investigation of Pulmonary Embolism Diagnosis II trial was a prospective, multicenter investigation of the accuracy of multidetector CTA alone and combined with venous-phase imaging (CTA-CTV) for the diagnos...
